Java serialization, the current mainstream codec framework, after the serialization of the code stream is much smaller than the native Java serialization;3) Poor serialization efficiency: in the same hardware conditions, the same Pojo object to do 100W serialization, binary encoding and Java native serialization performance comparison test as shown: Java native serialization time is 16.2 times times the binary code, the efficiency is very poor.Figure
ReentrantLock source code analysis for Java concurrent Series
Before Java5.0, only synchronized and volatile can be used to coordinate access to shared objects. We know that the synchronized keyword implements the built-in lock, while the volatile keyword ensures the multi-thread memory visibility. In most cases, these mechanisms work well, but cannot implement some more advanced functions. For example, the

Preface
In this article, we will discuss more details directly related to the execution context. The topic of the discussion is the this keyword. Practice has proved that this topic is very difficult, and this often occurs in different execution contexts.
Many programmers tend to think that in programming languages, the this keywo

According to the event source Event.target filter out the selector attribute of each element in the delegate event list handlers the node that corresponds to the delegate event between the event original and the delegate node document (including the event source) is saved as a handlerqueue;
Perform the event handling within the Handlerqueue.
The above is a rough process, followed by a detailed analysis. First look at the delegate sourc

describes three types of iterator adapters: insert iterator, reverseiterator, and iostream iterator. The latter two methods are more complicated in both implementation skills and understanding. Analyze it by using an instance. The Code is as follows:
Int main ()
{
1 ostream_iterator
2 int Ia [] = {0, 1, 2, 3, 4, 5 };
3 deque
4 copy (Id. Begin (), id. End (), outite );
5 cout
6 copy (IA + 1, Ia + 2, front_inserter (ID ));
7 copy (Id. Begin (), id. End (), outite );
8 cout
9 deque
10 reverse
that compilation is not a problem (the source code comment also says so ).
In addition, when initialization fails in the HostingInit method, there is a special line of code in the catch:
_hostingInitFailed = true;
This means that when the HostingEnvironment fails to be created, the HostingInitFailed of HttpRuntime will be assigned True. The concepts of preapplicationstartmethodattriator discussed later and the WebActivator entry have a relationship with this value. We will not discuss it here
